5. Asus PB287Q Monitor Rocks the 4K for $649

Asus will soon be selling 4K monitors — the high resolution monitors needed to view ultra-high-definition video — for $649.

Why? Because screen makers can make them very cheaply but guys like Sony and Samsung want to make a massive profit. Because the screens are hard to find in stores you’ll have to look for the Asus model PB287Q online (here’s a review, ships next month), plug in your computer, and get some high-def goodness.
